Change all <input> elements with forEach not working

Can someone explain, what's wrong with this?:

// 6: Change all <input> elements from text fields to checkboxes
document.getElementsByTagName('input').forEach(li => li.type = 'checkbox');

forEach works with arrays. getElementsByTagName returns a collection. Based on solutions provided in this stack overflow you could use the following:

[...document.getElementsByTagName('input')].forEach(li => li.type = 'checkbox');

Thank you, I guess it would make more sense to use the for loop, then..
